USGSThe best gradation of coal fine is mainly coarsegrained grade, followed by finegrained grade, and the middlegrained grade is the smallest When the coal fine particle size is too concentrated to the upper or lower limit, this will reduce the briquette strength The briquette pressure should be less than the crushing force of the coal 4 main factors that will influence the coal briquette quality
